Description

This one caused a lot of troble for me.
First and foremost, my mount doesn´t work as it should anymore. The RA-axis all of a sudden had a coupe of mm "play" during the session. 
Thus, the entire image is not actually sharp. The stars a very elongated and the only way to display the image is as a starless version.
I again used the TeleVue 2.5x to adjust FoV. To get somehow enough light to the sensor I used exposure times between 900s and 1200s for the outer nebula. For the bright core 5s and 15s were used.
After repair of the mount I will need to add nore light. S/N is still bad.
To add insult to injury I poured water over my keyboard during processing. So I needed to replace the keyboard.

Anyways, I am not so unhappy with the result of the core.
